If you're installing it new, you'll also need to pull a permit and for that you'll need a survey and you'll need to include the fence plan on the survey. Which, of course, then means that its subject to inspection and of course penalties when they find some nitpicky thing that you did wrong. Just make sure that you look at the county and state law for whatever zone you're in and you'll be fine.
Troll? LOL at permits to put up a fence. You call the power company and cable company to verify that there aren't any buried lines and come mark them if there are, then you put up your damned fence. This isn't the freaking burbs.
